Nine studies considered the association between body image and physical activity.
· A majority of the studies suggested that higher levels of physical activity led to better body image in their participants (1), especially in adolescent males (3,7).
· AN RCT of 110 non physically active adolescent girls showed an increase in self-perception and social anxiety scores after a 6-month exercise intervention programme (9)
· A meta-analysis including 114 articles, 4 of which were RCTs demonstrated significant positive associations between physical activity and self-image (8)
· Body image should not be the main driver to perform exercise as this has an association with an increase in self harm (2). A careful approach should be undertaken when suggesting exercise in children with body image concerns, since this may risk potentiating pre-existing body dysmorphia in this vulnerable population.
· A large evaluation of 5453 students showed there was no association with the intensity of physical activity and body image, suggesting even moderate levels of physical activity would have a positive association with body image (4)
Quality of Evidence
B. Mix of study designs contribute to the evidence, which includes meta-analysis, RCTs and longitudinal with cross-sectional analysis.
Strength of Recommendation
1 Strong recommendation, from a range of robust study designs including meta-analysis, RCTs, longitudinal studies
There is a strong recommendation from moderate evidence that participation in physical activity can improve body image. Although it should not be the focus on why children and adolescents take part in physical activity as this can have negative effects.
